Question

Which statement about conduction of electricity is correct?

Options

• Electricity is conducted in aqueous solution by electrons.

• Electricity is conducted in a metal wire by ions.

• Electricity is conducted in a molten electrolyte by electrons.

• Electricity is conducted in an acid solution by ions.

Answer 1

Electricity is conducted in an acid solution by ions.

Explanation:

Acid solutions are electrolytic conductors, meaning they split into free, mobile ions which carry the electric current through the liquid.
